Oral rehydration salts and diarrhoeal diseases: effects of changing inpatient management in Tonga.

Methods of inpatient management of children with diarrhoeal diseases (DD) in 1978 and in 1980 were compared to assess the use of oral rehydration salts (ORS) and a national antidiarrhoeal programme (NAP). Inpatient notes of 369 children admitted with DD were reviewed. The management of DD differed significantly but the clinical outcome was similar, with the exception of the case-fatality rate. All deaths occurred within the first 24 h of admission, indicating that this difference was attributable to improved management of DD in the community rather than changes in the inpatient treatment regime.

Seasonality of vital events in a Pacific Island population.

Analyses of vital data derived from a family record register for the native population of Guam reveal significant variations in births, deaths, and marriages over the period 1901-41. Although lacking marked photoperiod or temperature changes of temperate zones, the tropical island is subject to marked seasonal differences in rainfall characteristic of western Pacific islands. Marital patterns exhibit troughs associated respectively with the Lenten period and with Christmas celebrations. Infant and childhood deaths show close correspondence with rainfall patterns, consistently exceeding expected values during the rainy season (July-November) when conditions are optimal for the spread of communicable and gastrointestinal diseases. Births attain a peak in November, or at the beginning of the more advantageous season for infant health and survival. Seasonality in vital events, reported for many Euroamerican and some African and Asian populations of modern and historical periods, has rarely been documented for native populations of the tropical Pacific. Comparisons of differences in these patterns among different populations in varied environments provide unique opportunities to evaluate causal models of interactions among biological, sociocultural, and physioenvironmental factors.

Is lactation nature's contraceptive? Data from Samoa.

Data from a Samoan menstruation study suggest that lactation, even intensive on-demand lactation, does not inhibit menstruation or conception. This paper explores the applied and theoretical implications of continuing to accept lactation as a universally effective fertility control mechanism. Such thinking can have disastrous implications for family planning programs, and it keeps us from challenging long-held assumptions about lactation's role in population growth in early populations.

Seroepidemiological characterization of a syphilis epidemic in the Republic of the Marshall Islands, formerly a yaws endemic area.

The annual numbers of reported cases of syphilis in the Republic of the Marshall Islands (RMI) increased from none in 1983 to more than 600 in 1989, suggesting a large outbreak of syphilis. Much of the increase resulted from expanded serological screening. The apparent outbreak of syphilis, therefore, may have been partly the result of increased surveillance or, since the RMI was formerly a yaws endemic area, possibly due to a resurgence of yaws. To address this problem and better characterize the epidemic, we analysed results from a 1989/90 Ministry of Health Services mass serological screening on Majuro Atoll, the main population centre. Serum specimens from 9160 people (86% of residents aged 15-44 years) on Majuro were screened with the rapid plasma reagin (RPR) card test; we repeated the RPR and performed a confirmatory microhaemagglutination assay for Treponema pallidum-specific antibodies (MHA-TP) on a sample of serum specimens. To estimate the seroprevalence of syphilis, we also tested a sample of RPR nonreactive specimens by MHA-TP. Among people less than 45 years of age, total (11.5%) and high-titre (5.2%) seropositivity rates were highest in the 20-24 year age group, as was MHA-TP seroprevalence (15.9%). These results suggested that a large outbreak of syphilis was responsible for the observed seroreactivity. Cumulative incidence modelling and comparisons with the results of a previous serosurvey conducted in 1985 suggested that the duration of the syphilis epidemic was approximately 10 years and that incidence had not increased appreciably since 1985.

[Epidemiological surveillance of infection by the human immunodeficiency virus (HIV) and of the acquired immunodeficiency syndrome (AIDS) in French Polynesia in 1991].

The authors make out a statement about HIV infection in French Polynesia at the date of 1991 December 31. 96 cases all together of seropositive and AIDS infected people were recorded. These patients are young generally (78 p.c. between 21 and 40 years old) sexually contaminated (72 out of 96) and live in Tahiti island (94 p.c.). Sex-ratio is 2.8 male/1 female. Among them, we noted 55 p.c. of Europeans, 38 p.c. of Polynesians and 7 p.c. of Asiatic people. Epidemiological monitoring of the infection was made easy because of a set of laws and possibilities of detection highly favourable. Progress of the infection is constant, with 20 new cases detected each year with a prevalence of 150 cases of AIDS per 1 million of inhabitants, French Polynesia could be classified as the 5th or 6th region of France as far as the importance of the disease. Clinical, biological and epidemiological taking of charge of patients is detailed as well as the prevention campaign.

Confusion of trimester and viability. Consequences for abortion laws in the United States and abroad.

The present U.S. abortion law, Roe v Wade, is based on the trimester/viability concept. However, both concepts seem to be biologically ill founded and are likely to contribute to confusion regarding abortion laws. A survey of the abortion laws in individual states revealed a lack of uniformity. The time limit for abortion upon request varies from 13 to 28 weeks; nine states have no specific abortion law. This confusion also exists in other countries. Standards are lacking regarding requests for the dates of the last menstrual period, fertilization and implantation. Some states do not allow termination of pregnancy for maternal indications after 24 weeks, and the definition of maternal endangerment has rarely been addressed and remains vague. Only a few states have provisions for fetal malformation. Such terms as trimester and viability are not biologically founded and are likely to contribute to the confusion. The terminology should be clarified so abortion, contraception, birth control and other such terms are uniform.
